Fig. 8,'.is avieWof the smoothing tool shown in Fig. 7 looking; .from the leit oft' thelatter ligure. Fig. 9, is a plan oli' a discharge nozzle employed on thetool shown in Fig'. 7. Fig. 10'is a View' in side 'elevation' of theAdevice shown in Fig. S). Figs. 11-to 15 inclusive are details of aJfour-way valve employed in connection with the device shown in Fig. 3.Referring specifically to the drawings reference numeral 1 denotes abase on which the mechanism is mounted and this base is preferablycrucif'orm in shape and provided v with lateral extensions 2 and 3.

Mounted on the hase 1 is a .hollow housing -f't provided with end walls5 and 6 and further provided with side walls 7, and 8. These side walls7 and 8 are inwardly inclined toward each other and at the upper endsare outwardly ifiared to form a table in which is alongitudinally-extending groove 10. Secured to the lateral portions ofthev table 9 are inwardly-extending strips 11 to thereby convert thegroove 10 into a channel or way for the longitudinal shifting or' acarriage to be later described.

Slidably mounted in the channel 10 is a' carriage denominatedv generallyby the ref- 7 erence numeral 12 comprising a base plate 13 of' propersize to he received in thechannel 10. Extending upwardly from the loa`seplate 13 are a plurality of frames 14, v15, 16, and 17 arranged in pairswith the frames 14 and 15 constituting` one pair and With frames 16 and17 constitutingthe other pair.

These frames and their acconfipanyingl mechanism are identically similarland hence a description connected with one pair, say for oit' one pairof frames is believed to he suf- 10'5 cient, and it may be here statedfor brevity that the machine shown in Fig. 1 is a duplex device and themechanism-on opposite sides of a vertical line drawn centrally through iinstance the frames 14 and 15 is believed to 100 the base 1 are similarand hence theA descripv11o tion will be confined to mechanism on the .inFig. 1. The frames 14 and 15 are provided with laterally projectingbrackets 1.8 in the outer portions of which are open bearings to receivethe projecting ends of a shaft 19 bearing a stockroll 20 on which iswound a supply of rubber coated or impregnated fabric alternating' witha lining strip for preventing adhesion of successive layers of strips toeach other, Projecting laterally from the frames 14 and 15 are a pair ofoppositely disposed bearings 21 in which is a shaft 22 bearing a frame23 carrying a takeup roller 24 onto which the lining strip originallywound on the stock-roll 20 is wound as the strip of tirebuildingmaterial is unwound from the stock-roll 20. Near the lower portion ofthe frames 14 .and 15 and extending laterally therefrom are two brackets24 oppositely4 disposed to each other and each providedwithL-a bearingfor a shaft 25 on which is a tension roll 26, see Figj2. On oppositesides of, and' below the shaft 25, the brackets 24 are provided withapertures constituting bearings for shafts 27 and 2S on which areguiding rollers 29 and 30 respeotively. Both shafts 25 on opposite sidesof the frames 14 and 15 bear flanged pulleys 31 to` receive brake-bands32 preferably connected with eachother through the medium lof acoil-spring 33. The brake-bands 32 on the peripheral faces of theflanged pulleys 31 create suliicient friction on the'pulleys 31 toretard the rotation of the roll 26 and this frictional braking orresistance to rotation is constantly insured by' means of the coilspring33. I

ln operation a stock roll 2O provided with alternate winding ofshoe-building material and a lining strip is placed in the bearings inthe brackets 18. and the shoe-building strip is carried downwardlyaround the guiding roller 29 and thence. upwardly over around theguiding roll 20 to the forming core, to be described. It is contemplatedthat the strength-giving threads of the stock roller supported by frames14 and 15 will be positioned at right angles to the 'strength-givingthreads of the stock rollers supported by frames 16 and 17 and in orderto shift these two frames longitudinally of the device to bring themalternately into alinement with the forming core to which theshoe-building-stock is carried, l employ the following mechanism:Depending from the under-face of the base plate 13 is :n

bracket 34 provided with an aperture to receive a piston rod 35 equippedat its outer end with a piston head 36 and adapted to reciprocate in acylinder or motor 37 secured to the end wall 5 of the housing 4. rEliecylinder is provided at one end with a port 38 Aandat its opposite endwith a port 39.

Lacasse The piston rod 35 extends through a suitable opening in the wall5 and the cylinder 37 is provided at opposite ends with stops 40 forlimiting the movement of the piston head and the carriage hearing theframes carrying the stock rollers. Extending from the port 38 is' a pipe41 and a pipe 42 leads from the'port 39. The inner ends of the pipes 41and are connected with a fourway valve denominated generally by thereference numeralv 43 as shown in Figs. 11 to 15, inclusive. The valve43 comprises the usual casing .having a socket 44 to receive the pipe 41and a socket 45 to receive the pipe 42. The falve proper is controlledby an operating handle 46. The casing is also provided Ywith an inletopening 4'? connected with a supply of a fluid under pressure such asair or water and is also provided with an exhaust opening 48. When thevalve. operated by the handle 4G is in the position shown in Fig. 2 thesupply inlet is connected with the pipe 41 and the port 3S for movingthe piston to the right in Figs. 2 and 8.

-When the valve is in the position shown in place with respect to theexhaust Huid in the pipe 41 when the valve is in the position shown inFig. 13 both the inlet, exhaust and the pipes 41 and 42 are closed andthe valve is then said to be in its neutral position.

Mounted within the (,:liainher inelosed b v the housing 4 is asupporting platform, seel Fig. 1, on which is mounted an electric motorltlie armature shaft of which is provided with a bevel-gear 52. The wall7 I i is provided with an iiiwaidly-extending the tension roll 26 andthence downwardly" ranged to seat in the opening in the projection andis held against movementI thereby. This tube-like member providcwl atonelend with a head. 55 bearing a cen trally-positioned bearing and atits oppo site end with a head 5G the latter provided with a bearing inalinement with the bearing in the head 55 and in these two bearings ismounted a. rotatable shaft 5T. The shaft 57 bears at one end abevel-gear 58 arranged to intermesli with the gear 52 on the arma-- tureshaft of the motor 51. The shaft 57 bears at its opposite end aspur-gear 59. Also mounted in the head 5G a stub shaft 60 bearingaspur-gear 61 interineshing` with the gear :59.

The, frame extends laterally lOO Manasse l from the inwardly-projectingtubular ,pore

t1on 54 to form a portion 62 abutting against the outer face o ff the'wall 7. From the vportion 62 projects an arm 63 lfrom which extendsflanges 64 and 65. In the flange'65 and the portion 62 are bearings fora rotatable shaft 66. The shaft'66 bears a loosely-mounted gear 67intermeshing "with the gear 61 and receives motiontherefrom. The gear 67is provided with a hub 68 forming one member of a clutch. Splined on theshaft 66 is the companion memberV of the clutch 69 which is providedwith nogs engaging a clutch operating lever 71 fulcrumed at 72 on thearm 63. The

. Shaft 66 also bears a bevel-gear 73 positioned between the flanges 64and 65;.' The arm 63 carries a wide bearing 74 in which is mounted arotatable shaft 75 on which is a bevel-gear 76 intermeshing with thebevel- 'gear 73. The outer free end of the shaft 75 bears la chuck 77 ofVthe ordinary type used for supporting rotatable ring-cores i and on thechuck is a ring-'core 78.

carriage 81 is outwardly inclined and thev upper portion is providedwith -a way 83 for a carrier 84 shiftalole'towa-rd and away from thecore 78. rI he under-face 'of the upper portion of the carriage 81 isprovided ton falls it draws the belt 92 downwardly.

its closed position by a spring 95.

with a pair of depending bearings 85 in which is a rotatable shaft 86bearing at one end an operating handle 87 and at its oppo site end aflanged drum 88. .Positioned below the drum 88 is a cylinder 89, seeFig. 5 in which is a piston 90 carrying a piston-- `rod 91 to the end ofwhich is connected .a belt 92 attached to the drum 88 and run-- ningenthe peripheral surface thereof. EX- tending through the piston 90 is anopening'93 arranged to beclosed iby a downwardly-opening valve 94normally heldI1 iln e upper and lower portions of the cylinder areprovided with ports, connected with which are pipes 96 and 97 in open.communi` cation-with a three-way valve 98. v f

.The operation and function ofthe cylinder 89 and the ycarrier 84 areasfollows :--A fluid such for' instance as water is admitted to the upperportion tof the cylinder above the piston 90 and the water orotherfluid' will cause the piston to descend, provision being made bythevalve -93 for the escape of the fluid below the piston and as' the pisqand rotates the-drum y88 and shaft86. '1 l1e shaft 86'bears aspur-pinion 198 meshmg with the teeth of a rack 99 on .face of thecarrier 84 and thisengagement of the pinion 198 with the rack 99 willshift the runder the carrier-84 to the left in Fig. 6. v-This movementof the carrier will be a relatively slow movement and the'speed ofmotien of the carrier 84 can be regulated by the flow of-luid throughthe pipe'96 into the cylinder 89 above the piston 90. For reasons whichwill appear later it is preferable'that the carrier 84 be shifted to theright "at a considerably greater speed than' its movement to theleft andfor this purpose the operating handle v87 is employed whichrap--y drum88-and raises idly rotates the 'shaft 86, the piston 90- with equalspeed andfthis movement is further permitted by the'fact that as thepiston 'm0ves upwardly the valve 94 will openallowing the fluid abovethe piston toY pass through the ,opening 93 tothe chamber below thepiston;

Secured t0 the under face of .the carrier A 84fby holding means 100 arebracket-s'flOl' L-shaped in cro-ss-section-with the upwardlyi.

projecting .portions spaced'fro'm the front working edge 102 of thecarrier and provided with rack teeth 103. These two .brackets 101 arepositioned one on each side of the transverse median line of the carrier84..'

.Oppositely disposed to each bracket 101 and positioned on the upper.face ofthe carrier 84 and in alinement with each .otherare two brackets104 and 105. The faces of the brackets 104 and 105 which oppose the rackteeth 103 of the brackets 101 constitute bearingsurfaces for Atherolling movement of a pair of sleeves 106 one of whlch is positioned inthe channel between one of the brackets 101 and bracket 104 and theotherin the channel between one of the. brackets 101 and the bracket.105. these sleeves constitute broken gears each having a pluralityof-teeth 107 arranged to 'intermesh with the rack teeth 103. The

sleeve-s and their connected mechanism being similar thedescription'will be confined to one and similar reference numerals willindicate similar parts in the two mechanisms. Each sleeve surrounds anupwardly-extending sleeve-like standardlllOS provided with anppening 109constituting a bearing to re-` ceive a non-rotatable hollow'shaft 110one end of which is provided with threads 111 to receive a flexible pipe112. Rotatably `mounted on the shaft is a combined air distributingl andspinning rollV forssmoothing and placing the shoe-building material onthe core. This smoothing-tool comprises a hub 113 revolving on the shaft110 and has an enlarged head 114 the outer portion 115- of which iscapable of'engagementwith the .fabric on the core for the smoothing andvshaping thereof. The front face of the head 114 is recessed and has aplurality of blades or buckets 116 of -in'volute curvaturefor a Theperipheral faces ofpurpose to be later described. The head 114: issecured in position by means of a cap or nozzle 117 held inplace byscrews 118 and having a radially-extending discharge opening 110. rjlhestandards 108 are provided with inwardly-projecting arms 120 providedwith' postsy 121 to which are secured coilspr-ings 122 anchored at theiropposite ends to posts 123 O'nthe upper face of the carrier 84.

Positioned above the core 78 is a discharge nozzle 125 connected with apipe 126 see Fig. 2 in which is a valve 127. rfhe pipe 126 may besupported by a suitable bracket 128.

The pipes 112 and 126 are connected withl a source of fluid, such asair, under high pressure for a purpose to be laterl described.

The operation of the device is as follows, and the description willb'eiconfined to the mechanism on the night side of the ilnaginaryVvertical line drawn centrally of the' housing in Fig. 1: 'slwbfstockrolls equipped with alternate windings of tire-shoe building materialand lining are placed in the bearings in the brackets 18. 'The fabric onthese two rolls is preferably so formed or arranged that thestrength-giving threads'r cords of the fabric on one roll will be atapproximatel'y right angles with respect to the strength-giving threadsof the fabric on the other roll and the two rolls are arranged to .bebrought/alternately into alinement with the core 78 by manipulating thcvalve 43 aS has already been described, and this manipulation consistsin shifting the position of the carriage 12 carrying the two frames14:-15 and 16-17 laterally in the channel 10. The fabric on the stockroll in alinement with the core 78 is usually the first one employed andthe stock is unwound from the stock roll and .carried downwardly aroundthe guiding roll 29 over the tension roll 26 andA around'the guidingroll 80 and applied to the core 78 as shown in Fig. 1. The cere is thengiven one complete revolution by i mea-ns of the motor 51 and therevolution of the core may be controlled through the medium of theclutch lever 71. The surplus of i yunemployed stock is cut from theapplied 59 strip and the ends of the strip are trimmed 'so as to form anabutting or lapping joint.

' The clutch lever 71v is then manipulated to cause a rotation of thecore 78 and the speed of its revolution may be controlled bv the motor51. When the strip or layer 124 is applied to the core only the outertread portion thereof will adhere to the core and this adhesion may beassisted and increased by 'directing a jet of air from the nozzle 125during the applying of the fabric. In order to' smooth down, shape andfashion the side portions of the strips along the sides of the core rIemploy the two spinning-rolls 114 which are brought forward by movingthe valve 98 to its open position to admit a fluid to the, cylinderSl'above the pistoh 90 which causes7 the pistonvl 90 to descend therebyrem volving the drum'88 and the shaft 86, which 1bears the pinien 198intermeshing with the rack teeth 99 resulting in a movement of ythecarrier 84 toward the..core. As the carrier moves slowly due to theincreasing quantity of fluid in th-e cylinder above the piston 90, thespinning rolls engage the fabric on the core and receiving motiontherefrom, the conoidally-shaped peripheral portions smooth the fabricdown and shape it about the outer face of the core in order to form theshoe.

The spinning rolls 101 will be held in 'snug engagement with thetire-slice stock on the core by the tension of the springs 122 whichconstantly tend to swing the spinning rolls inwardly toward each other,their revolution being permitted by the fact that the standards aremounted in the sleeves 106 and if during the movement of the carrier 84inwardly toward the core it becomes necessary for the spinning rolls 114to move outwardly to accommodate themselves to the constantly changingsurfaces -thereof and also to cause the spinning rolls to standapproximately radial to the curvature of the core body the sleeves areforced outwardly substantially in unison and the teeth 107 during theoperation intermesh with the teeth 103 and the opposite faces of thesleeves 106 run against the faces of the brackets 1041L and 105. Itiscontemplated that the spinning rolls 104; will gradually be forcedinwardly toward the inner portions of the core and in4 doing so theyltraverse all of the surfaces of the plies or layers on which they rolland constantly maintain themselves in relatively radial positions withrespect to the center of the curvature of the outer face of the corebody. Experience has shown that during the rapid revolution of the corethe unsecured or unadhered portions of the strips of the tirebuildingmaterial on the core are thrown outwardly by the centrifugal force dueto the revolution of the core and also excess material along the innerportions of the core have a tendency to buckle, and form plaits whichmust be smoothed out by the tools in order to form a perfect tire-sliceand experience has also shown that in the placing of these plies duringthe building of tireslioes that air bubbles frequently occur. In orderto obviate these various difficulties arising in the construction of atire-shoe I force through the hollow shaft 110 by means of the supplypipe 112 a blast of-air or other suitable fluid under high pressuredirected outwardly through the opening or slot 119 in the nozzle 117against the blades 11G in the recessed open end of the spinning rolls114:. The opening in the nozzle 119Will-be so directed that the jet ofair greatly assist and aid the Lacasse vthemselves out and attach to thecore in ad-l vance of thespinning rolls 114; and thereby smoothing andshaping of the fabric Aabout the core. By utilizing the blasts of air inopposite sides of the core to force the unsecured portions of the fabricto the core in advance of the smoothing orspinning rolls 114 the latterare enabled to act more quickly and with better results and lessliability of injuring the fabric and producing bubbles in thecoiistruction of tire-shoes and they alsov obviate the danger ofdamaging-the fabric,tliis last i result being an unusually important onefrom the fact that frequently when blasts of air are not employedlaterally against 'the outwardly Haring side portions of the strip offabric on the rapidly revolving core the fabric is likely tobecomeentangledthe understandin Ptheplacement of each layer loftire-shoe,-

i6@ applied layers. In fact any arrangement of with the spinning rollsand buckle up to form objectionable places inv the product which is tobe produced. `When the carrier 84 has been moved by the weight of thefiuid in the cylinder 89-to its inner position the handle 87 is manuallymanipulated and the carrier returns to its original outer po sition ashas been already described and a second layerof fabric is applied to thecore following theoperation described lwith reference to the firstlayer. The number of layers and the' placement of the beads on thetire-shoe being unimportant it is thought that a description thereof isunnecessary for of this invention. After building lmaterial on the coreit is preferable to shift the `position of the carriage 12bynianipulating the valve 43 so as to bring one stock roll intoalinement with the core 78 which has windings lof fabric thereon, thestrength-giving threads of which are at substantially right angles withrespect to the strength-giving threads of the last applied layer anddui-ing the buildingup of the tire-shoe this shifting of the position`of the carriage 12 can take place at will so that if it is desired toplace two layers of fabric on the core insuccession with thestrength-giving threads thereof extending in parallelism the carriagecan remain sta- -tionaiy and then can be shifted to put on two morelayers with the strength-giving threads thereof in parallelism witheacli lother but at right angles with respect to the strength-givingthreads of previously the layers can be hadas desired and the operatoris not compelled by utilizing thisin- `vention to alternate thedirection of the f strength-giving threads of succeeding `laycore, stockrolls ers and he is entirely at liberty and is en;4
